ROBERT H. RAWLS, OF IVOR, VIRGINIA.

TRACK-CLEANER FOR SAWMILL-CAREIAGES.

To all whom it may concern Be it known that 1, ROBERT H. Rmvrs, a citizen of the United States, residing at Ivor, in the county of Southampton and State of Virginia, have invented certain new and useful Improvements in Track-Cleaners for Sawmill-Carriages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in saw mill appliances and relates more particularly to track cleaners and Wheel guards for saw mill carriages.

One of the objects of the invention is to provide a track cleaner which will prevent all kinds of foreign matter collecting on the tracks of the saw mill carriage and thereby insuring a steady movement thereof.

Another object of the invention is to provide a track cleaner and wheel guard, comprising a hollow body adapted to partly surround a wheel of a saw mill carriage and provided with removable wear strips and track engaging elements so that when these parts become worn, they may be easily and quickly replaced so that the expense of an entirely new device will be saved.

With these and other objects in View, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure l is a side elevation of my device, showing the same as it appears in use, Fig. 2 is a transverse sectional view taken on the plane of line 2-42 of Fig. 1, Fig. 3 is a vertical sectional view, through the device, the saw mill carriage being shown in elevation and partly broken away, Fig. 1 is a section taken on the plane of line 1- 1 of Fig. 3, and, Fig. 5 is a section taken on the plane of line 55 of Fig. 3.

Referring in detail to the drawings by numerals, 6 designates a portion of a saw mill carriage, 7 one of the wheels thereof, and 8 one of the track rails upon which the carriage runs. These parts are shown for the purpose of showing the manner in which Specification of Letters Patent.

Serial No. 781,347.

my improved track cleaner and wheel guard is used.

The device comprises a hollow oblong body or shoe which is preferably cast in two pleces.

9 designates the spaced parallel side walls of the body, and 10 the end walls thereof. The side walls are cut away centrally of their ends adjacent their upper edges to provide the essentially semicircular recesses 11. The body is also cut away upon each side adjacent its ends, as indicated by the numeral 12 and the end walls 10 have their inner faces inclined downwardly and inwardly, as clearly shown in Fig. 3. These inner faces are formed with longitudinal dove-tail channels 18, to receive the wheel engaging strips 1 1, which are shaped to conform to the channels 13. These strips engage the periphery of the wheel 7 and prevent foreign matter collecting thereon. The side walls 9 are formed upon their inner faces with dove-tail channels 15 to receive the wear strips 17 which engage the sides of the wheel 7. The channels 15 extend longitudinally of the body adjacent the top thereof and terminate at the re cesses 11 so that the strips 17 may be easily positioned and removed.

The body or shoe is formed upon its under side adjacent its ends with channels or recesses 18 in which the reduced portions 19 of the track engaging elements 20 extend. Bolts 21 extend through the body sections and the reduced portions 19 and hold these members in proper position. Nuts 22 are threaded upon the ends of the bolts, as shown in Fig. 2. The tops of these track engaging elements, as will be apparent upon reference to Fig. 3, close the lower ends of the channels 13 and support the strips 1 1.

My device when in use is free from any connection with the saw mill carriage and rests upon the track rail 8, being moved therealong by the wheel 7 bearing against one or the other of the blocks 14-. Since the body is formed in two similar sections, it may be easily positioned about the carriage wheel by placing the sections on opposite sides thereof and extending the bolts 21 through said sections and through the track engaging elements 20. The track engaging elements prevent shavings, saw-dust, and

other foreign matter accumulating on the track and the strips 14 and 17 keep the wheel free from all foreign matter. It will be noted that when these last mentioned members become worn they may be easily and quickly replaced.

From the foregoing description taken in connection with the accompanying drawings, it will be evident that I have provided a very strong, simple, and cheaply manufactured track cleaner and wheel guard for use in connection with saw mill carriages and one in which all of the parts which will become worn through use are removable.

It is to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall within the spirit and scope of the invention as claimed.

Having thus described my invention, I claim l. A track cleaner and wheel guard including a hollow body adapted to inclose the lower portion of a wheel and having side walls, said side walls being centrally recessed adjacent their upper edges and formed with longitudinal channels openlng upon the recesses and upon the inner faces of the walls, and removable wear strips secured within said channels for engagement with the sides of said wheel.

2. A track cleaner and wheel guard including a hollow body adapted to inolose the lower portion of a wheel, and having side walls, said side walls being centrally recessed adjacent their upper edges and formed with longitudinal channels opening upon the recesses and inner faces of the walls, said channels being positioned adjacent the upper edges of the side walls and being of a less length than the width of the recesses, and removable wear strips position ed within the channels for engagement with the sides of the wheel, said wear strips be- ROBERT H.
